View Full Version : "Check Engine" alarm keeps going off

Has anyone had experience with the engine alarm sounding on a 197 MCX A couple of months ago the alarm was sounding with no apparent fault. Oil, Temp, and Battery gauges all read normal. So we immediately pulled the boat out and took it to the dealer. They placed a new impeller in the water pump and new thermostat and reset the computer. We have used the boat 5-6 tomes since and it has been fine until today when it sounded again. We are thinking it may be a faulty sensor or maybe wiring problem. Has anyone had similar problems or know the cause? or more importantly the cure.

The dealer should be able to interigate the computor and give you a diagnostic code error that caused the alarm.

Here was my issue. I have a 197 MCX also with a very similar issue. I would go months without the buzzer/check engine and suddenly it would go off.
